A tornado watch was issued until 9 p.m. Tuesday from the Oklahoma-Texas state line northward through Kansas and into southeastern Nebraska and about 12 million people in an area from Oklahoma to Minnesota and South Dakota could see severe weather.
The Storm Prediction Center in Norman, Oklahoma, says central and eastern Kansas and north-central Oklahoma are at the greatest risk with baseball-sized hail possible in the Wichita area and straight-line winds of up to 75 mph.
Forecasters say an "isolated but important tornadic storm" is possible in southern Kansas or northern Oklahoma.
October tornadoes are less common than spring storms, but not unheard of. The Storm Prediction Center says 40 tornadoes were recorded in October 2015.
